Algebra 1 Vocabulary

Where do I find the zero of a function?

• Where the graph crosses the y-axis

• At the highest or lowest point of a Quadratic function

• Where the graph crosses the x-axis

• Where the graph approaches but does NOT touch

Answer explanation

A zero is also called an x-intercept, it is also called a root or a solution

What key feature is the initial value of a function?

• The y-intercept

• The x-intercept

• The vertex of the function

• The rate of change

What is another word for the Rate of Change of a function?

• The vertex of a line

• The slope of a line

• The y-intercept of the line

What is the vertex of a Quadratic Function?

• The point on the opposite side of a line

• The highest or lowest point on a graph

• The initial value of a graph

What is an Asymptote?

• An x-intercept

• An invisible line that a graph approaches but does not touch

• An invisible line that divides a graph in half

• The domain of the function

In order to Combine Like Terms, the polynomials must have...?

• A different variable and exponent
